I am not sure how this happened, but I joined a game randomly and it showed one of the player's hands (backwards, but still identifiable). It seems cards glitching out (between what is actually played vs what a spectator sees) happens a lot for watchers.

Not sure if this is account specific or overall. Very nasty bug if friends watch other friends play.
Thanks,
